Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • This invention relates to medication storage containers, and more specifically relates to a secured medication storage unit for storing and dispensing controlled substances in emergencies.
  • 2. Description of the Related Art
  • Individuals who are compelled by heath problems to rely on prescription medications must often make perpetual use of those medications at certain predetermined intervals for throughout their lives. An individual's non-receipt of certain medications, or inability to obtain them, can result in death, distress or permanent disfunction. This includes diabetics needing insulin and organ transplant recipients needing immunosuppressants, as well as heroine addicts needing methadone and psychiatric patients clinically addicted to antidepressants. Because these medications are controlled, and available only in small quantities at a time, any world wide natural or economic disaster which interrupted either the manufacture or supply lines of these medications would have devastating results on those reliant upon them. The possibility of a catastrophic event, and the legal inability of patients to stockpile needed medications, can be an ongoing source of anxiety, distress, fear and depression.
  • A secured device, which cannot be tampered with and which dispenses stockpiled medication at predetermined intervals, is needed in the art. Beneficially, this device might receive instruction from, or fall under the control of, a managing authority, such as a pharmacy, municipality or the FDA. This vault might be controlled via a computer network, such as a local area network (LAN) or wide area network (WAN). In some embodiments, this device might dispense medication to authorized personnel for subsequent dispersion to patients.
  • Some medication dispensing devices are known in the art. U.S. Pat. No. 5,912,818 discloses a medication dispensing device without heightened security. U.S. Pat. No. 6,163,736 discloses a tamper resistant programmable medication dispenser with some security features. The disclosed device utilizes an indexing wheel to supply medication at varied intervals for each day of the week the dispenser is in use. U.S. Pat. No. 6,382,416 discloses a medication safety storage system, which restricts access to medicines to authorized persons who have preprogrammed a micro processor to recognize their unique fingerprint. U.S. Pat. No. 6,415,202 discloses a tamper resistant programmable medicine dispenser, which incorporates a programmable timer and a device assembly for selectively indexing a plurality of separate containers relative to a dispenser outlet. U.S. Pat. No. 6,662,081 discloses a medication regime container and system, which includes a holder for multiple storing and dispensing units in an ordered fashion consistent with the daily requirements of a medication regime.
  • None of these devices provide security, refrigeration, or an interface with a controlling authority. What are needed are a device, system and method which do.
  • SUMMARY OF THE INVENTION
  • From the foregoing discussion, it should be apparent that a need exists for a tamper-proof emergency medication reserve repository.
